feat: support to bind to lan lazily and re-bind to lan

[mzz2017]

Background

Sometimes, we want to bind a LAN interface once it is brought up (NewLink).

For example, I want to bind dae to ap0 once I start to share my hotspot. However, I do not exactly know when in the future I will start to share my hotspot and create an ap0. dae will fail to start if fail to bind any LAN interfaces.

Another problem is that if my ap0 is deleted, when ap0 is created in the future, dae will not bind to it again.

This PR fixes it.
